If you have a cardholder style wallet and want to carry some cash with you, I highly recommend getting this clip. This way you don't have to stuff all your cash in the card holder and you can reduce the thickness of the pocket by putting this money clip in the side pocket and the card holder in the back pocket or vice versa. going, it's doing a good job of keeping the money together. It's also fairly easy to insert bills, although sometimes worn $1 bills get a bit torn in the process. Although there is no serious damage yet.
